Use Pythagorean theorem:
9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80
now divide both terms in V by that:
u = 9/sqrt(80)i - 1/sqrt(80)j

Answer:
The height of the triangle is always the measurement of a line (often shown as dashes) that is perpendicular to the base and extends to the opposite angle at the top of the triangle.
